English: Figure 1. (a) Myxoinflammatory fibroblastic sarcoma (MIFS). This was a multinodular neoplasm centered in the dermal and subcutaneous tissues of the foot. (b–e) There are nodular distributions of numerous atypical, multivacuolated fibroblasts within extensive myxoid stroma (Figure 1(b)–(e)). Also present are small numbers of moderately atypical spindle cells and large cells with prominent enlarged eosinophilic nucleoli (Figure 1(d)). Foci of hemorrhage are present (Figure 1(e)). (f) Hemosiderotic fibrolipomatous tumor (HFLT). Many areas show adipose tissue with intervening, moderately cellular fibrous septa containing mildly atypical spindle cells with hemosiderin pigment deposition. The transition between the areas of HFLT and MIFS ranged from gradual to relatively abrupt (shown here).
